Data Oriented Parsing (DOP) is a probabilistic performance approach to
parsing natural language. Several DOP models have been proposed since
it was introduced by Scha (1990), achieving promising results. One
important feature of these models is the probability estimation
procedure. Two major esti...

False beliefs involve attributing to another the attitude of belief
towards a counterfactual proposition. Here I have considered various
aspects of the attribution of false beliefs: firstly, that it involves
recognition of the possible non-existence or falsity of objects of
thought (objects are o...

From a computational perspective, parsing is a very interesting
phenomenon. All people do it quickly, and all people do it well. The
history of cognitive science has been filled with attempts to explain
the mechanisms that guide the human sentence processing mechanism
(hf. HSPM). These have ty...

Scenarios for the Pass\'e Simple and Imparfait
An Event Calculus Approach to French Semantics
Fabrice Nauze
Abstract:
The goal of this thesis is to apply an AI technique for planning to natural
language semantics (pragmatics). It could seem strange at first sight to
relate both areas but let us ...

This thesis is about the preservativity logic and provability logic of
Heyting arithmetic (or HA). Our interests in this thesis are not
about iPH or iH itself but about some natural sub-logical systems of
iPH and iH. We attain some conservation results relating these
preservativity and provabili...

Stemming is a process which provides a mapping of different morphological variants of words into their base/common word (stem). This process is also known as conflation. Based on the assumption that terms which have a common stem will usually have similar meaning, the stemming process is widely u...

Roughly speaking, in this thesis we will propose a logical system
merging update logic as conceived by A.Baltag, L.Moss, S.Solecki on
the one hand; and belief revision theory as conceived by C.Alchourron,
P.Gardenfors and D.Mackinson (viewed from the point of view of
W.Spohn) on the other hand. B...

The sharp increase in the amount of easily accessible information in
the last decade resulted in a growing amount of research regarding
information extraction and retrieval. Inside the general information
retrieval framework, specialized methods emerged for specific domains,
trying to exploit fea...

In this thesis, I introduce and investigate a new framework for modeling epistemic information in games that allows to express more general types of uncertainty than, for instance, imperfect information. In particular, we liberate the view on epistemic alternatives: not just other states of the s...

Automatic question answering (QA) has gained increasing interest in
the last few years. Question-Answering systems return an answer rather
than a document. Definitional questions are questions such as Who is
Alexander Hamilton? or what are fractals? Looking at logs of web
search engines definitio...

The Extensible Markup Language (XML) was designed to describe the
content of a document and its hierarchical structure. The XML Path
language (XPath) is a language for selecting elements from XML
documents. We propose and implement a linear embedding of
the query evaluation problem for Core XPa...
